Application filed April 24, 1888- Serial No. 271,711- (No model.) Patented in England September 17, 1885, No. 11,041,1'ebruary l3, 1886,1110. 2,113, January 5, 1887,N0.149, and January Z8,1888,N0.1,317.

To all 1071.012 it may concern-.-

Be it known that we, MARSHALL HENRY PEARSON and CHARLES BENNioN, subjects of the Queen of Great Britain and Ireland, residing at Leicester, in the county of Leicester, England, have invented certain new and useful Improvements in Punching and Eyeleting Machines, (for parts of which Letters Patent have been granted in England to the said llIARSHALL HENRY PEARSON, No. 11,0-11, dated September 17, 1885, and No. 2,113, dated Feb ruary 13, 1886; also to the said MARSHALL HENRY PEARSON and CHARLES BENNION, No. 149, dated January 5, 1887, and for which provisional protection has been granted to the said parties, No. 1,317, dated January 28, 1888,) of which the following is a specification.

This invention relates to improvements in punching and eyeleting machines such as are used in the boot and shoe trade for perforating and eyeleting the uppers of boots or shoes; and the objects of these improvements are, first, to provide means whereby a bootupper may be punched and eyeleted simul taneously, or each operation may be performed separately, on the same machine; second, to provide means for supplying a regular supply of eyelets to the clinching mechanism, and, third, to reduce the friction in moving the chute to and from its work. \Ve attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of entire machine; Fig. 2, a part front elevation with stand and treadle arrangement removed; Fig. 3, a side elevation of framing for carrying the punching mechanism; Fig. 4, a part plan on line ac, Fig. 1; Fig. 5, a plan of the lower part of the stand as it appears after the pillar has been removed; Fig. 6, an enlarged section on line y y, Fig; 1; Fig. 7 ,a part plan of machine, looking at the top; Fig. 8, a plan of work-supporting horn. Figs. 9 and 10 are respectively a side and front elevation of self-feeding eyeleting mechanism. Figs. 11 and 12 are respectively a plan (with lid removed) and a front elevation of eyeletbox; Figs. 13 and 1 1, an elevation and a plan (with cover removed) of eyelet-controlling device; Fig. 15, a cross-section of eyelet-chute on line 20, Fig. 10. Figs. 16, 17, 18, 19, 20, and 21 are respectively enlarged side and front elevations of mechanism for actuating the chute; Fig. 22, mechanism for returning the treadles to their original position. Figs. 23, 2 4, 25, and 26 are respectively elevations and plans of the treadlcs, Figs. 25 and 26 being drawn to a larger scale than Figs. 23 and 21. Figs. 27 and 28 are a side elevation and front elevation of device for increasing the distance between the punching and eyeleting spindles. Figs. 29, 30, and 31 are a side elevation, front elevation, and plan of work-supporting horn adapted for a machine to be fixed on a bench.

Similar letters refer to like parts throughout the several views.

The standard A, its pillar B, and legs C constitute the frame-work of the machine. In the bosses to a slides the spindle D, carrying the eyelet-clinching die d, and to the upper end of the former is attached, between the collars d, the bifurcated end (1 of the bent portion of the connecting rod or lever (1 which rod or lever is connected at its opposite or straight end to the treadle referred to hereinafter.

To the standard A is mounted and hinged at a a a second and smaller standard or framing, E, carrying the punching mechanism, in such a manner that the distancebetween the punch and eyelet-clinching tools can be readily adjusted by the regulating-screw and lock-nut c, Fig. 2, as well as by the lever ar- .rangement c, Fig. 27. The two standards A and E are retained in relative positions to each other by a spiral spring, 6 attached to the pins a and c In the bosses e 6 slides the spindle F, carrying a punching-tool, f, of ordinary construction, and to the upper end of the former is attached, by a setscrew, the bent portion of the connecting rod or lever f which is coupled at its opposite end to the treadles referred to hereinafter. The connecting-rods d and f are made to work, respectively, in the vertical recesses (0 and 6 formed in the standards A and E, Fig. 7, and are retained in position by the plates a and e Set-screws a and 6 are provided for regulating the stroke of the rods or levers d and f Thespindles D and F are preferably mounted in their bosses out of center, and the spindle F is also provided with the elongated end f, in which the punching-tool is fixed, so as to permit of the latter and the eyelet-clinching tool working closely together; but when holes of two different pitches are required to be punched in a boot-upper the distance between the two spindles may be instantly increased by means of the lever device shown at Fig. 27, which consists of pivoting the lever e to the boss e of the standard E, and when it is desired to increase the pitch of the holes the lever is raised, which causes its cam-shaped end to operate against the end of an adjustable screw, a, (carried by the lug (r of the standard A,) until the recessed end 6 impinges on the end of the screw. The distance between the two spindles may be readily adjusted by the screw C612. To the bracket b of the pillar B is bolted the work-supporting horn G, which is curved, as shown, to make room for the boot or shoe upper to be passed under the punching and eyeleting tools. In the upper portion of the horn, centrally with the spindle, is the fixed clinching eyeletingdie d This die may be vertically adjusted in the horn, and may be retained after adjustment by a set-screw, g. In some cases, when the machine is required to be fixed to a bench instead of a pillar, B, as shown at Fig. 1, the horn may be shaped as shown at Figs. 29, 30, and 31, and cast to the same foundation-plate, I), as the eyeleting-standard A is screwed. The foundation-plate U is bolted to a sole-plate, Z), which is fixed to the bench. To the seating or projection a is secured the bracket h, to which is hinged, at h, the selffeeding mechanism for supplying the eyelets to the clinching device referred to hereinafter.

The means we employ for arranging, regulating, and conveying the eyelets to the clinching-dies consists of a square or rectangular flat-bottomed box, (with or without the hinged lid 71 hinged to the bracket h by means of a pin, h? To the latter is also hinged a vertical chute, I, in such a manner that an intermittent reciprocating motion may be imparted to these parts from the spindle D, either separately or simultaneously, as hereinafter described.

The box H, reciprocated by the spindle D, and shown at Figs. 9, 10, 11., and 12, is divided into two compartments, the lower one being preferably, though not necessarily so, made narrower and shallower than the upper one. Over the lower compartment is secured a plate, h, which forms the bottom of the upper compartment, and communication between the two portions is obtained by means of a hole, 71 formed in the plate slightly out of center and near the rear end of the box, as shown at Figs. 9 and 11. This hole is covered by a shield, .I, made in two partsviz.,

a conducting portion or guide, j, a little deeper than the length of the eyelets and shaped somewhat similar to a nautilus shell, (see Fig. 13,) and a cover, j, secured to the upper portion of the guide j. (See Fig. 14.)

The guidej placed with its mouthj facing the front of the box, and it is employed for regulating the passage and supply of eyelets from one compartment to the other.

To the front of the previously-referred-to box II is secured an angular plate, K, which, after being secured to the front of the box, is bent at a right angle thereto, so as to pass through the slit or opening 75 into the lower compartment, parallel with and immediately under the plate 71;, until it is turned down at right angles to form a guide plate or comb across the lower compartment and nearly its full depth. In this guide-plate k is cut or formed a number of holes or recesses of the same shape as the eyelets, and so arranged that the latter can only pass under and through this plate to the chute with their barrels uppermost. In some cases this angleplate may be dispensed with, and openings or perforations of the shape of the eyelets may be cut or formed in the end of the box; but we prefer using the angle-plate, as we find the eyelets pass more regularly to the chute when there isa short distance between the plate 76' and hinge h.

The chute I, previously referred to, and shown at Figs. 9 and 10, is provided at its upper hinged end with a hopper, i, for receiving the eyelets as they pass from the lower compartment of the box H. The chute is bent at its free or delivery end to pass between the clinching-dies. To the back or body 1' of the chute is secured the guiding-plates 1N placed at a suitable distance apart, so as to form a channel, 2', down which the barrel of the eyelet slides on its way to the clinching-dies, while the flanges of the eyelets impinge and slide down the body '6. That part of the inner edge of each guide-plate i nearest the body is well rounded off, so as to provide a free and clear passagefor the eyelets down the channel 1". The portion of the chute which works on the pin h is made concentric therewith and forms a hinge with the lower compartment of the box H. These two parts are so arranged that whateverposition the box and chute assume as regards each other the upper surface of the lower compartment is at a tangent with the periphery of the hinge. The outer portion of the hopper is formed by a removable plate or covering, 2' having its upper end made concentric with the hinge. The upper portion of the guide-plate 2' is inclined, as shown at Fig. 10, to aid in conducting or directing the eyelets to the channel. A spring, 1' is secured to the lower end of the chute to prevent the eyelets from escaping therefrom, except when acted upon by the nipple d and spindle D.

The chute I is intermittently reciprocated by the spindle D, to allow the latter to perform the clinching opera-tion. This movement of the chute is obtained by a roller, (1 fixed to the spindle l), (see'Figs. 18 and 19,) or carried by a separate plate, d, (see Figs. 16 and 17,) which is operated by a pin at tached to the spindle D. hen the latter device is adopted, the plate (1 is made to work in the recesses a, Fig. '7, in the standards A, and held in that position by a flat spring, (1 The roller (Z acts upon a cam or projection, (Z secured to the body i of the chute, either at the free bent end, as shown at Figs. 9,18, and if), or else near the center, shown at Fig. 115. \Vhen the cam-piece (i .is placed near the bent delivery end of the chute, it is so shaped that as the spindle moves downward the roller will slide upon the face without moving the chute. As soon as the nipple cl enters the eyelet (retained in the end of the chute by the spring i) the roller is timed to come in contact with the lower projecting portion, (1", of the cam and push the chute on one side clear of the spindle until the clinching operation has been completed. \Vhen the clinching operation has been performed, the spindle D commences to rise and the projecting portion (1 remains in contact with the roller (/5 until the lower end of the spindle has risen clear of the free delivery end of the chute. Then the roller passes 011 to the parallel portion of the cam and allows the chute end to again pass under the nipple. The spring (Z is employed for retaining the cam in contact with the roller.

lVhen the eyelet-clinching die (I and nipple d are fixed in the spindle out of center, as shown at Figs. 9, 20, and 21, for the purpose of punching and eyeleting holes much closer together, and at distances suitable for the uppers of ladies and childrens boots and shoes, we use a projection, (W, in place of the roller (1 This projection is fixed to the spindle D and acts upon the previously-referredto cam (i in the manner described.

The chute I may be thrown in. and out of action by means of a OL111l6V61,(Z Fig. 27, which is pivoted at d to the chute. \Vhen the end (1 is made to act upon the lug or projection a of the standard A, as shown in dotted lines, Fig. 27, the cam d and roller d are disengaged.

The eyelet-clinching device consist-s of an upper die, (I, secured to the spindle D, and a lower die, (1", secured in a recess in the horn G, as previously explained. The upper die, cl, which is inserted in a hole, d, bored up the spindle 1), (see Fig. 19,) is provided with a hole through its center to form a bearing for the nipple d. The nipple is provided with a head, (1 of a rather less diameter than the hole L1 In order to dispense with the spiral spring which usually acts on the nipple, a slit, d, is cut in the latter from the head downward to about one-half its length. The split portion is sprung open,-so that it will impinge and hold by friction against the walls of the hole in the die and by the head in the hole (Z of the spindle. In the spindle is also formed or cut a slot-hole, (1, through which is passed at right angles to the spindle a pin, (1 fixed in the hearing a. This pin is employed to prevent the nipple from rising with the spindle to the full extent of the stroke of the latter. As soon as the head of the nipple comes in contact with the pin (1 the former remains stationary, while spindle continues its upward motion, thereby forcing the free end of the nipple outward, ready to receive the eyelet (at the end of the chute) on the return or downward stroke of the spindle. The nipple after passing through the eyelet remains in this outward position until its free end has passed through the eyelet and is brought in contact with the lower die, d. It is then forced with the die (1 and spindle, and rests there until again acted upon by the pin (1 as described. By this means the danger of the end of the chute coming in contact with the nipple is removed.

L L are the treadles for operating, respectively, the spindles 1) and F through the rods 61 and f The treadles are pivoted to the legs 0 at c, and connected to the screwed portion of the rods (7. and f by trunnion-nuts Z Z, whereby the stroke of the said spindles can be readily adjusted. To provide for any inaccuracy in the working of the two treadles, the foot-plate Z Fig. 23,"o'f the lever L,which operates the punch, is secured 011 one end of the flat spring Z, while its opposite end is fixed to the lever L, as shown at Figs. 23 and 2a, thereby permitting the foot-plate to be depressed with the treadle L without acting upon the punching-spindle F. In order to raise the treadles after each operation to their normal position, spiral springs c1 (Z f Figs. 9 and 22, may be employed. To adjust the position of the springs (Z and f on the rods 61 and f movable collars (Z and f are employed, which are held in position by setscrews, as shown. Spring (1' made to encircle the spindle l).

The action of the machine for punching and eyeleting boot or shoe uppers is as fol lows: After the chute has been thrown out of action by the cam-lever d the box H (the upper compartment of which has been previously filled, or nearly so, with eyelets) is reciprocated or tilted by the treadle L, through rod (1 and spindle D, until the channel in the chute is filled with eyelets. During the tilting operation each time the rear or free end of the box is depressed the bulk of the eyelets will be thrown to that end of the box, and one, two, or more of the eyelets will enter the mouth of the guidingshield J. The eyelets, after entering the shield, are passed round to the curved part j ready to be thrown forward when the box returned to the position shown in the drawings. As these eyelets are thrown forward toward the hinge, they are prevented from passing beyond the hole 71 111 the floor 71 of the upper compare ment by means of the semicircular end j of the shield that partially surrounds the hole, and are thus passed from one compartment to the other. After the eyelets have been passed through the hole 7L5 they are again shaken an d turned over in the lower compartment by the continued tilting operations until their flanges rest fiat upon the inner surface of the lower compartment. \Vhen in this position, they slide forward and issue through the apertures in the plate and through the opening 75, over or round the hinge it, into the hopper i, and from thence down the channel "i to the delivery end of the chute I. After the chute has been filled with eyelets the tilting of the box ateach clinching operation will keep the chute constantly supplied. As the eyelets pass over the curved or bent portion of the free end of the chute they are reversed, so as to be delivered to the clinching-dies with their tlanges uppermost. It will be readily observed thatby having the chute circular or curved at both ends the eyelets are completely turned during their passage from the lower compartment of the box to the clinching-dies, while their flanges are kept in contact with the body or foundation plate 6 of the chute until they reach its delivery end. \Vhen the chute has been returned to the position shown in the drawings, we commence at the vamp of the upper and punch a hole by depressing the treadle L. Then the upper is passed to the left hand until the hole just punched is passed over the fixed eyeleting-die d in the horn G.

. This hole is then eyeleted and a second one punched by depressing both treadles at the same time, whereby the spindles of both machines are operated simultaneously and the eyelets also supplied to the machine, as herein described. Each hole after being punched is passed over the fixed eyeleting-die and the eyeleting and punching operations continued until the last hole is punched, when this hole is eyeleted by depressing treadle L.

In conclusion, we are aware that prior to our invention separate machines for punching and eyeleting boot or shoe uppers have been made with vertically-sliding spindles operated by fulcrumed levers; also, that Letters Patent have been granted in England to William Robert Lake, (a communication from Mellen Bray, of Boston and Newton, Massachusetts, United States,) No. 100, dated J anuary 12, 1875, and No. 2,333, dated June 9, 1880, in the specifications of which a tilting box hinged to a chute is employed for supplying and conducting a special. kind of rivet (used in the boot trade) to a cylinder to be drilled, and also to a fixin g-m aehine. \Ve therefore do not claim such combinations, broadly; but
